a car travels 180 km in 2 hours on a straight road.
how many km can the car travel in 210 minutes at the same speed?
First, we need to convert 210 minutes to hours. There are 60 minutes in an hour, so 210 minutes is equal to 210/60 = 3.5 hours.
Now we can use the formula for speed: speed = distance / time.
We know that the speed is constant, so we can set up the equation:
180 km / 2 hours = x km / 3.5 hours.
Simplifying this equation, we get:
2 * x = 180 * 3.5,
which becomes:
2x = 630.
Dividing both sides by 2, we find:
x = 315 km.
Therefore, the car can travel 315 km in 210 minutes at the same speed.
